About

Highlight any passage on an AO3 work page, add a private note, and continue reading. Your notes remain saved locally in Chrome until you clear them. When you reach the end, the extension compiles your selected passages and reactions into one formatted comment that you can copy or insert directly into AO3’s comment box.

Features include:

Add notes to highlighted passages
Save notes across chapters of the same work
Restore notes and highlights after refreshing or reopening the work
Edit or delete individual notes
Compile all notes into one comment
Insert the compiled comment into AO3 for review
Clear notes manually when finished
Store all notes locally in your browser

AO3 Margin Notes does not collect, transmit, or sell user data. It runs only on AO3 work pages and uses Chrome storage solely to retain your notes.

AO3 Margin Notes is an independent browser extension and is not affiliated with or endorsed by Archive of Our Own or the Organization for Transformative Works.
